BTC006 is a 6.5 mm miniature capsule slip ring.This ultra-compact size miniature slip ring delivers stable transmission of power and signals between rotating and stationary components - ideal for modern devices where space is extremely limited and performance cannot be compromised.It carries power or signal through a rotating joint in tight spaces such as drones, camera gimbals and small instruments. It runs 4 to 12 circuits at 1A per circuit, up to 240V, with gold-to-gold contacts for low noise.

Standard leads are 250 mm 32AWG Teflon wire. Circuit count and lead wires can be changed to fit your design.

OD 6.5mm Miniature Slip Ring Key Features

Ultra-compact design

Only 6.5 mm outer diameter, perfect for micro-mechanical systems, portable instruments, and miniature gimbals.

Multi-circuit capability

Supports up to 6–12 circuits for power, analog, or data signals.

Low electrical noise

Uses gold-to-gold contact technology for stable signal transmission and minimal resistance fluctuation.

Lightweight & low torque

Extremely low friction torque ensures smooth rotation and long service life.

Wide operating range

Works reliably in temperatures from -20 °C to +80 °C

Why Choose BTC006

6.5 mm outer diameter

Fits drones, gimbals and small instruments with little room to spare.

Gold-to-gold contacts

Low, steady contact resistance for clean power and signal.

Low noise (≤7 mΩ)

Works with analog and sensor lines.

4–12 circuit options

One body covers several channel counts.

250 mm leads

Enough wire to route during prototyping and small runs.

IP54, −40°C to +80°C

Handles dust, splashes and a wide temperature range.

Typical Applications

Drone & UAV gimbals

Passes power and signal across the gimbal joint while keeping the head small and light.

Camera stabilizers

Turns smoothly at 250 rpm with low torque, so it does not fight the stabilizer.

Medical instruments

Gold contacts and low noise keep signals clean in small imaging and diagnostic heads.

Miniature robotics

Fits small joints, rotating sensors and automation heads where space is the limit.

Testing & measuring devices

Keeps signal flowing to rotating probes and portable test equipment.
